Back in July I got my period on the 21, it lasted about 10 days until the 31. I had unprotected sex the 4 of august, my app says I was ovulating that day. August 14 I started to have a light bleeding, not quiet like a period because it didn't hurt which lasted about 3 days. Im just really confused, has this happened to anyone else? I recently took a test the day before yesterday And it was negative. My app says my period should be coming today, but it hasn't? Should I wait to take another test
